# Changelog
## 2025-08-18 - 4.2.1 - fix(gzip)
Improve gzip streaming decompression, archive analysis and unpacking; add gzip tests
- Add a streaming DecompressGunzipTransform using fflate.Gunzip with proper _flush handling to support chunked gzip input and avoid buffering issues.
- Refactor ArchiveAnalyzer: introduce IAnalyzedResult, getAnalyzedStream(), and getDecompressionStream() to better detect mime types and wire appropriate decompression streams (gzip, zip, bzip2, tar).
- Use SmartRequest response streams converted via stream.Readable.fromWeb for URL sources in SmartArchive.getArchiveStream() to improve remote archive handling.
- Improve nested archive unpacking and SmartArchive export pipeline: more robust tar/zip handling, consistent SmartDuplex usage and backpressure handling.
- Enhance exportToFs: ensure directories, improved logging for relative paths, and safer write-stream wiring.
- Add comprehensive gzip-focused tests (test/test.gzip.ts) covering file extraction, stream extraction, header filename handling, large files, and a real-world tgz-from-URL extraction scenario.
## 2025-08-18 - 4.2.0 - feat(classes.smartarchive)
Support URL streams, recursive archive unpacking and filesystem export; improve ZIP/GZIP/BZIP2 robustness; CI and package metadata updates
- Add exportToFs(targetDir, fileName?) to write extracted StreamFile objects to the filesystem (ensures directories, logs relative paths, waits for write completion).
- Implement exportToStreamOfStreamFiles with recursive unpacking pipeline that handles application/x-tar (tar-stream Extract), application/zip (fflate Unzip), nested archives and StreamIntake for StreamFile results.
- Enhance getArchiveStream() to support URL/web streams (SmartRequest) and return Node Readable streams for remote archives.
- Make ZIP decompression more robust: accept ArrayBuffer-like chunks, coerce to Buffer before pushing to fflate.Unzip, and ensure SmartDuplex handling of results.
- Fixes and improvements to bzip2/gzip/tar tool implementations (various bug/formatting fixes, safer CRC and stream handling).
- Update CI workflows to use new registry image and adjust npmci install path; minor .gitignore additions.
- Package metadata tweaks: bugs URL and homepage updated, packageManager/pnpm fields adjusted.
- Documentation/readme expanded and polished with quick start, examples and API reference updates.
- Small test and plugin export cleanups (formatting and trailing commas removed/added).
- TypeScript/formatting fixes across many files (consistent casing, trailing commas, typings, tsconfig additions).
## 2025-08-18 - 4.1.0 - feat(classes.smartarchive)
Support URL web streams, add recursive archive unpacking and filesystem export, and improve ZIP decompression robustness
- ts/classes.smartarchive.ts: add exportToFs(targetDir, fileName?) to write extracted StreamFile objects to the filesystem (ensures directories, logs relative paths, waits for write completion).
- ts/classes.smartarchive.ts: implement exportToStreamOfStreamFiles with recursive unpacking pipeline that handles application/x-tar (tar-stream Extract), application/zip (fflate unzip), nested archives and StreamIntake for StreamFile results.
- ts/classes.smartarchive.ts: improve getArchiveStream() for URL sources by using SmartRequest.create().url(...).get() and converting the returned Web stream into a Node Readable stream.
- ts/classes.ziptools.ts: make ZIP decompression writeFunction more robust — accept non-Buffer chunks, coerce to Buffer before pushing to fflate.Unzip, and loosen the writeFunction typing to handle incoming ArrayBuffer-like data.

# Using pnpm (recommended)
pnpm add @push.rocks/smartarchive
# Using yarn
yarn add @push.rocks/smartarchive
```
This will add `@push.rocks/smartarchive` to your project's dependencies.
## Quick Start 🎯
## Usage
`@push.rocks/smartarchive` is a powerful module designed to simplify the process of working with archive files such as zip, tar, gzip, and more. It provides an easy-to-use API for extracting, creating, and analyzing archives, making it an ideal choice for projects that require manipulation of archive files.
### Getting Started
First, import `SmartArchive` from `@push.rocks/smartarchive` using ESM syntax:
### Extract an archive from URL
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
// Extract a .tar.gz archive from a URL directly to the filesystem
const archive = await SmartArchive.fromArchiveUrl(
'https://github.com/some/repo/archive/main.tar.gz'
);
await archive.exportToFs('./extracted');
```
### Extracting Archive Files
To extract an archive file, you can use `SmartArchive.fromArchiveUrl`, `SmartArchive.fromArchiveFile`, or `SmartArchive.fromArchiveStream` methods depending on the source of your archive. Here's an example of extracting an archive from a URL:
### Process archive as a stream
```typescript
async function extractArchiveFromURL() {
const url = 'https://example.com/archive.zip';
const targetDir = '/path/to/extract';
import { SmartArchive } from '@push.rocks/smartarchive';
const archive = await SmartArchive.fromArchiveUrl(url);
await archive.exportToFs(targetDir);
// Stream-based processing for memory efficiency
const archive = await SmartArchive.fromArchiveFile('./large-archive.zip');

```
## Core Concepts 💡
### Archive Sources
`SmartArchive` accepts archives from three sources:
1. **URL** - Download and process archives from the web
2. **File** - Load archives from the local filesystem
3. **Stream** - Process archives from any Node.js stream
### Export Destinations
Extract archives to multiple destinations:
1. **Filesystem** - Extract directly to a directory
2. **Stream of files** - Process files individually as streams
3. **Archive stream** - Re-stream as different format
## Usage Examples 🔨
### Working with ZIP files
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
// Extract a ZIP file
const zipArchive = await SmartArchive.fromArchiveFile('./archive.zip');
await zipArchive.exportToFs('./output');
// Stream ZIP contents for processing
const fileStream = await zipArchive.exportToStreamOfStreamFiles();
fileStream.on('data', (file) => {
if (file.path.endsWith('.json')) {
// Process JSON files from the archive
file.pipe(jsonProcessor);
}
});
```
### Working with TAR archives
```typescript
import { SmartArchive, TarTools } from '@push.rocks/smartarchive';
// Extract a .tar.gz file
const tarGzArchive = await SmartArchive.fromArchiveFile('./archive.tar.gz');
await tarGzArchive.exportToFs('./extracted');
// Create a TAR archive (using TarTools directly)
const tarTools = new TarTools();
const packStream = await tarTools.packDirectory('./source-directory');
packStream.pipe(createWriteStream('./output.tar'));
```
### Extracting from URLs
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
// Download and extract in one operation
const remoteArchive = await SmartArchive.fromArchiveUrl(
'https://example.com/data.tar.gz'
);
// Extract to filesystem
await remoteArchive.exportToFs('./local-dir');
// Or process as stream
const stream = await remoteArchive.exportToStreamOfStreamFiles();
```
### Analyzing archive contents
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
// Analyze without extracting
const archive = await SmartArchive.fromArchiveFile('./archive.zip');
const analyzer = archive.archiveAnalyzer;
// Use the analyzer to inspect contents
// (exact implementation depends on analyzer methods)
```
### Working with GZIP files
```typescript
import { SmartArchive, GzipTools } from '@push.rocks/smartarchive';
// Decompress a .gz file
const gzipArchive = await SmartArchive.fromArchiveFile('./data.json.gz');
await gzipArchive.exportToFs('./decompressed', 'data.json');
// Use GzipTools directly for streaming
const gzipTools = new GzipTools();
const decompressStream = gzipTools.getDecompressionStream();
createReadStream('./compressed.gz')
.pipe(decompressStream)
.pipe(createWriteStream('./decompressed'));
```
### Working with BZIP2 files
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
// Handle .bz2 files
const bzipArchive = await SmartArchive.fromArchiveUrl(
'https://example.com/data.bz2'
);
await bzipArchive.exportToFs('./extracted', 'data.txt');
```
### Advanced streaming operations
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
import { pipeline } from 'stream/promises';
// Chain operations with streams
const archive = await SmartArchive.fromArchiveFile('./archive.tar.gz');
const exportStream = await archive.exportToStreamOfStreamFiles();
// Process each file in the archive
await pipeline(
exportStream,
async function* (source) {
for await (const file of source) {
if (file.path.endsWith('.log')) {
// Process log files
yield processLogFile(file);
}
}
},
createWriteStream('./processed-logs.txt')
);
```
### Creating archives (advanced)
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
import { TarTools } from '@push.rocks/smartarchive';
// Using SmartArchive to create an archive
const archive = new SmartArchive();
// Add content to the archive
archive.addedDirectories.push('./src');
archive.addedFiles.push('./readme.md');
archive.addedFiles.push('./package.json');
// Export as TAR.GZ
const tarGzStream = await archive.exportToTarGzStream();
tarGzStream.pipe(createWriteStream('./output.tar.gz'));
```
### Extract and transform
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
import { Transform } from 'stream';
// Extract and transform files in one pipeline
const archive = await SmartArchive.fromArchiveUrl(
'https://example.com/source-code.tar.gz'
);
const extractStream = await archive.exportToStreamOfStreamFiles();
// Transform TypeScript to JavaScript during extraction
extractStream.on('data', (fileStream) => {
if (fileStream.path.endsWith('.ts')) {
fileStream
.pipe(typescriptTranspiler())
.pipe(createWriteStream(fileStream.path.replace('.ts', '.js')));
} else {
fileStream.pipe(createWriteStream(fileStream.path));
}
});
```
## API Reference 📚
### SmartArchive Class
#### Static Methods
- `SmartArchive.fromArchiveUrl(url: string)` - Create from URL
- `SmartArchive.fromArchiveFile(path: string)` - Create from file
- `SmartArchive.fromArchiveStream(stream: NodeJS.ReadableStream)` - Create from stream
#### Instance Methods
- `exportToFs(targetDir: string, fileName?: string)` - Extract to filesystem
- `exportToStreamOfStreamFiles()` - Get a stream of file streams
- `exportToTarGzStream()` - Export as TAR.GZ stream
- `getArchiveStream()` - Get the raw archive stream
#### Properties
- `archiveAnalyzer` - Analyze archive contents
- `tarTools` - TAR-specific operations
- `zipTools` - ZIP-specific operations
- `gzipTools` - GZIP-specific operations
- `bzip2Tools` - BZIP2-specific operations
### Specialized Tools
Each tool class provides format-specific operations:
- **TarTools** - Pack/unpack TAR archives
- **ZipTools** - Handle ZIP compression
- **GzipTools** - GZIP compression/decompression
- **Bzip2Tools** - BZIP2 operations
## Performance Tips 🏎️
1. **Use streaming for large files** - Avoid loading entire archives into memory
2. **Process files in parallel** - Utilize stream operations for concurrent processing
3. **Choose the right format** - TAR.GZ for Unix systems, ZIP for cross-platform compatibility
4. **Enable compression wisely** - Balance between file size and CPU usage
## Error Handling 🛡️
```typescript
import { SmartArchive } from '@push.rocks/smartarchive';
try {
const archive = await SmartArchive.fromArchiveUrl('https://example.com/file.zip');
await archive.exportToFs('./output');
} catch (error) {
if (error.code === 'ENOENT') {
console.error('Archive file not found');
} else if (error.code === 'EACCES') {
console.error('Permission denied');
} else {
console.error('Archive extraction failed:', error.message);
}
}
```
### Creating Archive Files
Creating archive files such as zip or tar.gz is straightforward with `smartarchive`. At the moment, you'll prepare the contents programmatically and then compress them. Detailed support for creating archives will be covered in future updates.
### Analyzing Archive Files
Analyzing the content of archives without extracting them can be useful in various scenarios, such as when you need to inspect the archive's content before deciding to extract it. Here's how you might analyze an archive:
## Real-World Use Cases 🌍
### Backup System
```typescript
async function analyzeArchive() {
const url = 'https://example.com/archive.zip';
const archive = await SmartArchive.fromArchiveUrl(url);
const analysisResult = await archive.analyzeContent();
console.log(analysisResult); // Outputs details about the archive content
}
// Automated backup extraction
const backup = await SmartArchive.fromArchiveFile('./backup.tar.gz');
await backup.exportToFs('/restore/location');
```
Note: Replace `analyzeContent` with the appropriate method calls as per your implementation or update, as `smartarchive` provides foundational classes and methods for interaction with archive files but does not directly implement an `analyzeContent` method by default.
### Stream Operations
`smartarchive` offers streaming operations, allowing you to work with large archives efficiently. Here's an example of using streams to extract an archive:
### CI/CD Pipeline
```typescript
import { createReadStream, createWriteStream } from 'fs';
async function extractArchiveUsingStream() {
const archiveStream = createReadStream('/path/to/archive.zip');
const archive = await SmartArchive.fromArchiveStream(archiveStream);
const extractionStream = await archive.exportToStreamOfStreamFiles();
extractionStream.pipe(createWriteStream('/path/to/destination'));
}
// Download and extract build artifacts
const artifacts = await SmartArchive.fromArchiveUrl(
`${CI_SERVER}/artifacts/build-${BUILD_ID}.zip`
);
await artifacts.exportToFs('./dist');
```

'https://data.source/dataset.tar.bz2'
);
const files = await dataset.exportToStreamOfStreamFiles();
// Process each file in the dataset
```
